Ad4App
The blocker with ads in it. On purpose! Pick your time-wasting apps; opening one puts up a wall, and the only way through is watching one short rewarded ad in Ad4App, about 30 seconds. Everyone hates ads. That is the mechanism: the annoyance is the deterrent, and the app is free forever.
Coming to the App Store and Google Play. This page also hosts the app's privacy policy and terms.
